Answer:
D. Multiple antibiotic resistance genes.
Explanation:
A plasmid with multiple antibiotic resistance genes is important during cloning as it helps in selectivity of the specific clones during transformation of bacteria.
<em>Amoeba </em>is an example of an E<span>ukaryote.

The use of a thermophilic DNA polymerase such as Taq polymerase prevents the denaturation of the enzyme during the heating that is important to separate the newly synthesized strand. So using this enzyme simplifies the PCR technique and increases its efficiency.
Taq DNA polymerase is highly efficient, when it reaches the optimum temperature, it becomes fully functional. It also has a half-life of over two hours (at 92°C), high amplification capacity, and it can add upto 150 nucleotides per second. It is "special" enzyme because it comes from the bacterium Thermus aquaticus, which lives in hot springs. It is therefore thermostable even at high temperatures, while other polymerases (e.g. E. coli) are not.

The term used for the condition, in which the uptake of nutrients from the small intestine is impaired is malabsorption.
The malabsorption is a condition, in which the small intestine walls become unable to uptake the nutrients in the blood. This condition can be caused by many different reasons, which affect the wall of the intestine. These conditions include infections, trauma, celiac disease, and surgery. Some diseases such as Crohn's disease, pancreatitis (chronic), or cystic fibrosis is also responsible for the malabsorption.
